Abstract
Plastične mase su sintetski polimerni materijali koji nastaju polimerizacijom monomera. Polimerne mase razlikuju se prema razgranatosti, strukturnim jedinicama i ponašanju pod utjecajem topline. U prehrambenoj industriji su najzastupljeniji polistiren, polipropilen, polietileni i polivinil klorid u obliku tuba, boca, čaša, folija, vrećica. Polimerni materijali su ispitani na propusnost i UV zaštitu jer utjecaj svjetlosti i UV-Vis zračenja može negativno utjecati na kvalitetu materijala. U ovom završnom radu snimljeni su normalni i derivirani spektri nekih polimernih materijala gdje se jasno uočava razlika u spektrima, kao i prisustvo skrivenih spektara u deriviranim spektrima. Provedenim ispitivanjem se uočava da polipropilen pokazuje najveći postotak transmitancije za UV zaštitu, dok polistiren za propusnost vidljive svjetlosti.
Abstract (english)
Plastic packagings are synthetic polymeric materials formed by the polymerization of monomers. Polymeric packagings differs in terms of branching, structural units, and heat behaviour. In the food industry, polystyrene, polypropylene, polyethylene and polyvinyl chloride are abundant in the form of tubes, bottles, glasses, foils and bags. Polymeric materials are tested on transparency and UV protection because the influence of light and UV-Vis radiation can negatively affect the quality of the material. In this work, normal and derivative spectra of some polymer materials were recorded, and the difference in spectra and the presence of hidden spectra in the derived spectra was clearly observed. In this work, polypropylene showed the highest percentage of transmissions for UV protection, while polystyrene for the permeability of visible light.
